thanks!

to clarify @martacus's answer, in case need replace // here item delete code should be accounts.remove(this) , you're in business.

you replace line

selecteditem?.apply{ accounts.remove(this) } 

with

selecteditem?.let{ accounts.remove(it) } 

from experience, let more common apply when using value instead of setting receiver.

note process different if accounts list constructed asynchronously , copied in, default behavior of asyncitems { accounts }.
